Bachmann Casts Herself As Thatcher-Style 'Iron Lady' In Last Iowa Ad

Repeating a theme she's been using frequently in recent days, Rep. Michele Bachmann's last TV ad before Tuesday's Iowa caucuses makes the case that she's an American "Iron Lady" in the style of former British Prime Minister Margaret Thatcher.

"Bachmann's transition from describing her 'titanium spine' to comparing herself to Britain's iconic 'Iron Lady' marks the congresswoman's closest flirtation with gender politics, something she has largely avoided in her long-shot quest for the White House.

"But it also raises questions about a possible gender barrier she could face in the closing days of Tuesday's contest in Iowa."
